A thin section or petrographic thin section is a type of laboratory preparation commonly used in geology, minerology, or petrography. Typically, a thin section is used to analyze a sample of rock, mineral, pottery, soil, bone, or even a piece of metal. A thin section is very beneficial when analyzing or assessing reservoirs. Publication Year: 1976: Title: The Reinhardt Thiessen coal thin-section slide collection of the U.S. Geological Survey; catalog and notes: DOI: 10.3133/b1432Typical thin section slides are 26 mm x 46 mm, although larger ones can be produced. They are generally covered by another glass slide, a cover slip also attached to the rock with epoxy. The epoxy ideally has an index of refraction of 1.54, although our epoxy is slightly higher, perhaps 1.56.
